ENGINE
Our Yukon was taken in for the recall. Dealer did the test and said it passed and used different oil. My wife and kids were driving to [XXX] from [XXX] yesterday. As they exited the highway, the car began acting weird. Then the car completely died. It was towed due to error code P0016. Dealer said they are going to put a new engine in. I saw online that cars with replacement engines were failing too? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL SYSTEM, GASOLINE
The contact owns a 2022 GMC Yukon. The contact stated that while attempting to make a left turn at an intersection, the vehicle lost automotive power while the accelerator pedal was depressed. The vehicle was towed to a local Firestone, where the fuel pump module was replaced. The local dealer was contacted. Upon further investigation, the contact associated the failure with GMC Emission Recall: N252516900-01; however, the VIN was not included. The vehicle was previously taken to another local dealer for a fuel pump module replacement. The manufacturer was made aware of the failure. The failure mileage was approximately 45,000.

ENGINE
My 2021 GMC Yukon began experiencing severe engine problems, including shaking/rough running, a noticeable ticking/knocking noise from the engine, and a flashing check-engine light. The vehicle also displayed Service ESC and traction control warnings and exhibited symptoms of an engine misfire. I took the vehicle to a dealership for evaluation. I was advised that the problem may involve failed lifters and that the vehicle could be out of service for several weeks for repairs. I was also advised that the repair could be very costly. At this time, I have not been given a final diagnosis, so the exact internal engine component responsible for the failure is UNKNOWN. I am concerned that the condition presents a safety risk because the engine is running extremely rough and the check-engine light is flashing. I am afraid the engine could lose power or fail while the vehicle is being driven, potentially putting me, my passengers, and other motorists at risk. I have also become aware of NHTSA's investigation involving failures of the 6.2-liter L87 V8 engine in GM vehicles, including the GMC Yukon, as well as reports of engine failures occurring after certain repairs or recall remedies. This has increased my concern about whether repairing or replacing individual engine components will permanently resolve the problem. I am submitting this complaint so that my vehicle's symptoms, dealer evaluation, and potential engine failure are documented. The vehicle and affected components are available for inspection upon request. The dealership has evaluated the vehicle, but a final determination of the exact cause has not yet been provided.

L87 recall was completed on 10/22/2025. On August 8th 2026 the engine developed a loud knock. It was taken to the dealership on 8/31/2026 after inspection it was determined that the engine had failed and needed to be replaced. There was no warning lamps that indicated there was an issue with the engine. The vehicle was still driveable when it was taken to the dealership. If the engine had completely failed while on the highway it could have caused a major incident.

POWER TRAIN
Sunday XXX, we were riding in our 2022 Yukon Denali with my wife driving on [XXX] at the speed limit of 75 mph when the vehicle stumbled for a moment then returned to normal operation... a few seconds later the engine just died. No drive information center warning or check engine light, no funny noises or catastrophic banging. It just quit running. There was traffic on the highway but with my wife's quick reaction we were able to get off the highway to the breakdown apron without crashing. We called AAA and had the vehicle towed to the GMC dealer (Oxendale GMC) in Flagstaff. We were at this point about 200 miles from home in [XXX] City. On Wednesday, XXX, the service writer called us and informed us the engine was seized and would have to be replaced. We were aware of the NTHSA recall and had taken our vehicle in on XXX to have the recall (N252494000) and at that time we passed the pico test and the oil was upgraded to the higher viscosity and oil fill cap changed. We were sent on our way with no advisory the recall may not have fixed the underlying problem. GM has agreed to replace the engine. We filed a complaint with GM (GM case #XXX) Since this happened, we have been looking into this situation and discovered ours is not an isolated case. A lawyer told us that here have been more than half a million vehicles recalled and an unknown number of catastrophic engine failures just like our, but NTHSA has received less than 1000 complaints. I wanted to make sure that my experience was conveyed to you. An additional note - we special ordered this vehicle new and began to have recurring electrical problems with it shortly after we took delivery. GM offered us a buy-back or a 100,000-mile warranty to keep the vehicle. Since then have had the vehicle serviced at regular recommended intervals by Brdley Chevrolet in [XXX]. We have repair invoices for every service and Recall repair done. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
While traveling at highway speeds of approximately 82 mph in a 2026 GMC Yukon Denali (6.2L V8 L87 engine), the engine experienced a sudden, catastrophic internal failure and completely seized without warning. This resulted in an immediate, total loss of motive power, power steering assist, and power braking assist while surrounded by high-speed traffic. The sudden deceleration and lack of vehicle control created an extreme, life-threatening safety hazard, forcing an emergency maneuver across multiple lanes to reach the shoulder. Stranded on shoulder at night(pitch black) with lots of 18 wheelers passing.

ENGINE, FUEL/PROPULSION SYSTEM
My vehicle was with ANCIRA GMC Boerne for approximately three weeks where they replaced the transmission control system/module, the centralized OnStar module, and diagnosed both rear screens for replacement. Approximately one month after getting it back, at only 49,800 miles, I experienced a complete loss of propulsion. The vehicle shut down while I was driving. Given the recent transmission repair and the fact that this failure occurred while the vehicle was in motion, I no longer have confidence in the safety or reliability of this vehicle. I have young children riding in this vehicle daily and I’m not comfortable accepting another repair and simply being told it’s safe to drive.

ENGINE
While driving my 2021 GMC Yukon Denali with the 6.2L L87 V8 on a high-speed highway near Somers Point, New Jersey, the vehicle suddenly began bucking and the accelerator stopped responding normally. The vehicle rapidly lost propulsion while I was surrounded by highway traffic and approaching a bridge. I was fortunate to get the vehicle onto the shoulder before reaching the bridge. I was then stranded on the shoulder of a high-speed highway, where the disabled vehicle created a serious safety risk to me and other motorists. The engine shut down and would not restart. It initially cranked as though it was attempting to start, but it did not start. I received a diagnostic alert stating, “Service the engine and transmission system immediately.” The vehicle required a tow. The tow operator later reported that it appeared locked up and could not be shifted into neutral. The vehicle has approximately 77,000 miles and has been serviced regularly. Its most recent oil-change sticker indicated the next oil service was due at approximately 81,000 miles. While safely pulled over, I checked the engine-oil dipstick and confirmed that the engine had oil, with oil visible across the dipstick’s normal measuring area. Despite this vehicle having the 6.2L L87 engine and experiencing a sudden loss of propulsion and no-start condition, its VIN does not currently appear in GM’s public recall lookup for the existing L87 recall. The vehicle is being transported to an authorized GMC dealer, and the precise failed component has not yet been confirmed. This sudden loss of propulsion created an immediate risk of a serious highway collision, particularly because it occurred immediately before a bridge. I understand NHTSA is investigating continuing L87 engine failures, including failures involving vehicles outside the original recall population. I am submitting this complaint so this incident is formally documented and considered as part of that investigation.

ENGINE AND ENGINE COOLING
The contact owns a 2023 GMC Yukon. The contact stated that while driving 65 MPH and depressing the accelerator pedal, the transmission shifted into neutral. The contact pulled over to the right side of the road and attempted to shift into drive; however, the failure persisted, and the vehicle lost power. No warning light was illuminated. The contact stated that the vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was serviced under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); by the owner of the vehicle, but the remedy failed to fix the vehicle. The contact stated that the failure had occurred after the recall repair. The manufacturer was notified of the failure and informed the dealer to replace the engine. The engine was replaced, and the vehicle was repaired. The failure mileage was 56,600.

ENGINE
My 2021 GMC Yukon Denali with approximately 88,000 miles developed a significant engine knocking noise and was towed to a GMC dealership for diagnosis. The dealership confirmed diagnostic trouble code P0301 (engine misfire) and documented a “knocking noise in lower end at piston rod crankshaft area.” The dealership advised that my vehicle is not currently included in the existing GM recall for certain 6.2L L87 engines. The vehicle has the 6.2L L87 V8 engine. I am concerned because the documented knocking is located in the lower engine area involving the piston/connecting rod/crankshaft area, which is consistent with the type of internal engine failure associated with the L87 engine investigation and recall. I am concerned about the possibility of sudden engine failure and loss of propulsion while driving. I am requesting that NHTSA investigate this failure and consider whether vehicles outside the current recall population should also be included. I also recently experienced an engine replacement on another 2024 GMC vehicle. I am providing that information as additional customer experience, but I am not claiming that the two failures are necessarily caused by the same defect.

ENGINE, FUEL/PROPULSION SYSTEM
My engine has failed twice. I am now on my third engine. The vehicle stalled while driving on a highway, was in the shop for nearly 3 months and was "fixed" with same 6.2 engine. Eight months later it stalled again was in the shop for 2 months with a new engine. I was informed that they still don't know the issue and they just put the same type of engine. A bandaid was placed in my vehicle and I'm suppose to feel safe in it.

this year model was recalled do to engine problems. Ours wasn't one that was on the recall list. We ended up having to have the motor rebuilt and cost us around $7000. We have seen where these models are still having problems, so i wanted to report our problem and the money spent to get it fixed.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While driving the vehicle on the interstate, the vehicle shifted to neutral without warning. Our daughter was able to fortunately coast to the side of the interstate without incident. The vehicle was shut off and attempted to turn back on without success, so vehicle was towed to Lugoff Chevy dealership where repairs are always performed. The dealership stated the problem was related to fuse block melted and shorted. The problem was fixed; however, I am not convinced that this shouldn't be something requiring a recall and needs further investigation. There was no warning lamps, messages, or symptoms prior to the failure.

ENGINE
A safety call was issued; NHTSA 25V274. GM found my engine needed to be replaced due to the recall. Transwest GMC in [XXX] replaced the engine at no charge in XXX. The new engine they put in, blew up while I was driving. It blew up in June 2026, about 6 months after the replacement was put in. Around 20k miles. Before they would even diagnose the engine failure, they made me provide service records. Which I did and was found to be compliant with their recommendations. They replaced engine again in XXX free of charge. However, now they are telling me that the engine is only covered up until 150,000 miles. At the time of engine failure, I had 127,000 miles on my car. Therefore, I would only have 23,000 miles left of coverage for a brand-new engine they replaced. I am filing a complaint because I am questioning their warranty. I am questing what the warranty is on safety recall. My car is 4 years old, and now I can't rely on it due to mutiple engine failures. It's questionable to me, why they will only cover it to an odometer reading of 150,000 when the engine is brand new. It seems they should cover the part itself for 150,000 miles. Especially when it's a known issue for certain GM motors right now. I am filing a complaint, in hopes that I can prevent someone from getting seriously injured. Also, to protect myself against future engine problems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
